Sealing the wood in limber holes

Curious,

I have to drill a couple of limber holes through the new stringer pieces on the 25 T Jason.

The limber holes on the old fir stringers were a simple 3/4" or 1" holes drilled and left the wood exposed.

When the old stringers were cut out to widen the the engine bed the exposed wood had absorbed quite a bit of water over the last 24 years.

How do you guys seal the wood grain inside a drain hole?

I can simply drill some holes and leave them "natural" and let the next owner deal with any structural issues "if any"......

but I like to do things more right than wrong.

Any suggestions?

Appreciated, Reelpleasure

 

On small holes, I drill the required size hole a little larger and then fill the hole with thickened epoxy and then drill the correct size hole through the epoxy. This is not likely possible for you now, but I would try to paint inside the hole with warmed epoxy so that it is nice and thin for absorption. You will need the wood to be dry so warm up with a heat gun as well. It may require several coats to seal as end grain will suck up quite a bit.

 

This is a double post. The other one is here.
